scinatien lreigningpit f Letters Patent Np. 53.9.42, 'dated october zo, 186s.

To allwhomtmay concernt vBeiitknown that 'LEN'ocn B. TURNER, of *Providence,` in thecountyo'f vProvidence and `State of Rhode Isl`and,"h`a`ve invented an' Improved Machine for Making Horseshoes; and

`I do hereby declare'thaty the following is a full and exact description thereof,`reference being hadto the accompanying drawings, making a part of thisspecification.l`

The nature of my invention consists in" a y the blanks to the proper length. The'knit'e T 1n achine' for cuttin' g off, formi ng up, and pressing horseshoes from a continuous bar of i'etal, or from a bar of shoe-blanks, formed byro'lls.

To enable those skilled in the art to make and use my invention, I will proceed to describe itsconstruction and operation.

The drawings represent a' double machine, capable of making two shoes at the same time.

Figure l represents a front view. Fig. 2 represents a side view. Fig. 3 represents a top view. Fig. 4 represents a squeezing-pad, as arranged to crease the shoe.

In this machine the movements required to complete the shoeare derived from the reciprocating movement of the saddles A A, moving uponthe upright guides It R, and operated by the cranks b b and connectingrods B B. I change'and adjust the length of these rods by means of the thimbles C O, containing a right and left hand screw, so that, by turning in one direction, the rod is lengthened, and by turning in the other it is shortened.

The saddlebars A A are made adjustable by means of the screws c c c c and Washers a j aa a, in order to accommodate the machine to shoes of different sizes or lengths.

D D are the rolls which operate the squeezin g-levers E E. These rolls are made adjustable by means of the connecting-rods P P, to be lengthened or shortened by means ot' the adjusting thimbles f f, with right and left screw. 4

G G G G are slotted formers, carrying the former-rolls H H H H. These rolls are made to form the shoes around the dies I I or mandrels, placed upon opposite sides of the anvil F, by means of the inclined or cam surfaces p p pp and adjustable rolls i i i i.

The springs j j operate to hold thc squeezing-levers E E against the rolls D D, and the OFFICE horns' or forks kk to pull the shoe from the die after it is finished. j 1

Mis the knife and gage holder, operated from the saddle-bar A by means of the slotted connectin g-rod K.

` L is the trimminggage, and N the butting gage,v either4 partaking of the` movement or acting in concert with theknife-holder M.

S an'dT are adjustableknives for cutting and batting-gage N are brought back to a central'position by the springs t t. Upon `the saddle-bars A' A" are the spurs m m m m, `wh ich operate to squeeze thev end of the blank before the shoe is turn'ed. The formers G G G G are connectedto the shafts g g by means of universal joints, allowing motion in any required direction.

O is a bar, containing a number of rolled shoeblanks, having upon the inner edge of the blank, in a central position, between the creases a a, a notch, o, for the purpose of determining the length of the shoe by means of contact in any suitable manner with the cuttingoff gage L.

The combination of these creases and intermediate notch in the center of the blank is ineluded in my invention.

In case the shoes are formed from a common bar of iron the squeezing-pad J, (shown in Fig. 4,) may be used, being arranged to stamp the creases in the shoe as it is formed.

In practice I prefer to use two machines in combination with a pair of rolls--one spa-re machine to be in readiness for use in case of accident to the other. They may, for this purpose, be placed on wheels, and be moved back and forth from the rolls upon a track. The iron is delivered from the rolls with any convenient number of blanks upon each bar, having in the center of each a gage-mark, by which the blank is to be gaged, so as to be out oft' from the bar and turned at an equal distance from the center of the shoe, thus preventing it from being formed unequally. This mark is a notch, of any convenient size, rolled into the creased face of the blank, and on its inner edge, bringing the mark directly over the concave of the shoe, as produced in the machine,

by which means the mark is obliterated. The iron is to be taken in a heated state immedieY ately from the rolls to the machine, the mark in the center of the forward blank being moved up to the gage. The knife trims off the surplus end while the machine is making the upward movement; but when the machine is making the downward movement, and the forming-rolls have come to a rest, the bar is to be moved across the machine until it strikes the batting-gage. The knife now makes a counter movement, cutting the blank from the bar. The blank is then squeezed upon the ends by the spurs upon the saddle-bars. Then begins the upward movement, relieving the knife from its extreme throw, and allowing it to assume a central position through the action of the springs for that purpose. As the saddles continue the upward movement the iormerrolls come in contact with the blank, and, b v their action, form it around the dies. Then the squeezing-rolls come in contact with the cam of the squeezing-levers, and, by their action, pressing the blank against the dies, complete the shoe, pass the highest part of the cam on the squeezin g-lever this lever is thrown from the die by means of the spring,` at its lower end, thus taking the finished shoe from the die by means of the horns or forks for that purpose.

shoe may be caused to drop upon an endless As the squeezing-rolls The belt, and by this means bc conveyed to any desired point.

Iam aware that for the use of springs in this machine could be substituted cams, driven from the main shaft, or levers and weights might be used. Therefore, I include all such devices as equivalents.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The arrangement and combination of the adjustable gage L, knife-holder M, adjustable knives T and S, adjustable batting-gage N, spring t, and slotted bar K, as herein set forth, and for the purposesr described.

2. The combination of the anvil F, mandrels I l, pads .l J, squeezing cam-levers E E, forks k k, and springs j j, all arranged as herein set forth, and for the purposes described.

3. The combination ofthe above devices with the cranks b b, adjustable shafts B B, saddles A A, saddle-bars A A', spurs m m m m, axle g g, adjustable connecting-rods P l), rollers D D, slotted cam-formers G G, former-rollers H H, and adjustable rollers fi fi, as herein set forth, all arranged and combined so as to form a complete machine for making horseshoes, as

described.
